I Thisfinvention relates to "apparatus for handling and transferringmaterials such, for example, as sheets or slabs. of builders boards andthe like. Among other objects, the invention aims toprovide an improvedapparatus of this character which will efiiciently and rapidlyhandlethematerials for which it is designed with a minimum of manuallabor and attention. I

The nature of theinvention maybe readily understood by reference to oneillustrative apparatus embodying the invention and shown in theaccompanying drawings, 111 which Fig. ratus; I

Fig. 2 is a side elevation of one end of the apparatus; and

Fig. 3 is an end elevation of the end of-the apparatus shown in Fig. 2.u

The illustrative apparatus is arranged, in this instance, for thedistribution and han- 1 is a perspective view of the appadling ofmaterials, builders boards, for exl largement 21 111 whichlongitudinally moving screw 22 is threaded to which, at one-end,

ample, to drying rooms, or to other apparatus for future treatment.Builders boards are usually prepared [continuous web by Well knownmachines adapted for that purpose. The board thus formed then usuallyrequires treatment,

drying, for example, to-renroveexcess molsture, and for this purpose 1t18 usually cut into sheets or slabs ofvariouslengths for convenience inhandling. These boards in the form of sheets or slabs are large andcumbersome and diflicult to handle and to turn and in many cases veryheavy, such, for example, as

boards formed of a cement and asbestoscomposition which in some mstancesare approxithe forming machine;

Fromthetormingmachine the sheets or slabs are placed in the lifting andhandling apparatus supported from an overhead moving crane, the liftingand handling apparatus s ias desired. Y I
